Travel from Sofia to Plovdiv

Hi Jon,

At that time of day I would recommend taking the bus. You can ride the metro from the airport to Serdika Station and then change lines (towards Obelya) which takes you to the central train station (the bus station is next to it). There is a bus to Plovdiv at least once every hour.
Good travel,

Thanks villagegirl! Someone has messaged me the same. Based on my extensive lack of local knowledge I will take the bus!  I've just checked the weather - it's going to be red hot

Personally, I prefer the train from Sofia to Plovdiv. I like being able to get up and walk around or open the windows and get a clear view of the countryside.

There is a train at 5:30 and another at 7:25. Avoid the 6:20 train as it is a slow train that stops at every village.

Everyone should experience a Bulgarian train!!! Do not look for 1st class compartments or any hospitality either on the platform, kiosk or attendant.
(the railway police in the station were very helpful as I went in asking who speaks "Anglo" they gladly pointed to one man but to be fair he helped me. 
That said my cross country hike from Sofia to Byala (slatini??) was an experience that will stay with me for quite a while, ha-ha now why did I get the coach back!!!
